Over the next several years, advancements in sensitivity and detector development for both High-Energy and Gravitational Wave (GW) observatories will revolutionize our understanding of some of the most extreme events in the Universe. In particular, the upcoming Fourth Observing Run (O4) of the LIGO-Virgo-KAGRA collaborations, expected to start in Spring 2023, will accelerate the growth of the multi-messenger astrophysics field, and lead to the discovery of new GW events to be followed up across the electromagnetic spectrum and with other messengers. The successful applicant will contribute to one or more of the following projects, depending on their interest and expertise: data analysis and interpretation of new GW transient events, targeted searches of continuous GW from known pulsars, directed searches of continuous GW waves from compact objects in supernova remnants and pulsar wind nebulae, follow-up and analysis of electromagnetic counterparts to GW events. Other projects that would align with multi-messenger studies of extreme astrophysical events can be proposed. The applicant will be given opportunities to (co-)supervise students, collaborate with researchers nationally and internationally, and contribute to outreach and Equity, Diversity and Inclusion activities at the University.

Applicants are required to have their PhD by the time they start their position, and preference will be given to candidates within three years of their PhD (official leaves not counted towards that timeframe). Applicants who are experienced with compact objects and gravitational wave (GW) astrophysics, GW data analysis, and/or follow up of electromagnetic counterparts of GW sources are strongly encouraged to apply and will be given preference. Knowledge of machine learning methods, Bayesian analysis, or surveys’ cross-matching will be an asset. This position will be full-time employment at the University of Manitoba with a negotiable starting date, ideally in May 2023, or soon after for a period of two years. A third year is possible subject to funding and performance.

The eXtreme astrophysics group of Prof. Safi-Harb collaborates with researchers nationally and internationally on multi-wavelength studies of high-energy astrophysical objects and phenomena; and is actively involved in the planning of future missions, particularly in the high-energy domain.
